Unformatted text preview: Remember: Temperature and salinity determine the density of seawater Thermohaline Circulation: Deep ocean circulation driven by temperature and salinity (density) Types of water masses: • Surface water • Intermediate water • Deep water • Botttom water Where do bottom, deep and intermediate waters form? Where do they come back up to the surface? Locations of water mass formation Remember the Gulf Stream – an arm of the N. Atlantic Gyre? The Oceanic Conveyor Belt links thermohaline circulation and surface currents in to one large system, moving heat and salt around the globe....
